PROBLEM TO BE SOLVED: To provide a method of utilizing heat energy in a cement manufacturing apparatus by which the clinker firing efficiency in a cement firing process and the availabilit of heat energy in a waste heat power generating apparatus are improved and the quantity of a waste gas discharged from the cement firing process to the atmosphere is decreased, and to provide the cement manufacturing equipement. SOLUTION: The method of utilizing heat energy is one in the cement manufacturing apparatus provided with the cement firing apparatus provided with a cement kiln 1 and a high efficiency type clinker cooler 31 and the waste gas powder generation system 32. A clinker is cooled by the high efficiency type clinker cooler 31, heated water obtained from a feed water heater 34 is supplied to the waste heat power generation system 32 and a part of the waste gas discharged from the feed water heater 34 is recycled as cooling air of the high efficiency type clinker cooler 31.
